    36.2 L is the volume of the gas

    Explanation:

    We apply the Ideal Gases Law to solve this:

    P. V = n. R. T

    Pressure: 1 atm

    V: Our unknown value

    n: the number of moles, 1.65 mol

    R: Universal Gases Constant (0.082 L. atm/mol. K)

    T: Absolute T°, is the T° in K (T°C + 273) → - 5°C + 273 = 268K

    Let's replace:

    1 atm. V = 1.65 mol. 0.082 L. atm/mol. K. 268K

    V = (1.65 mol. 0.082 L. atm/mol. K. 268K) / 1 atm → 36.2 L
